使用HTMLunit获取ajax/javascript内容

我已经编写了一个代码，它将获取页面的html内容作为响应，我正在使用html单元来实现这一点。但是我得到了一些特定URL的错误，比如

[https://communities.netapp.com/welcome][1]

对于第一页，我能够检索内容。但当我不知道的内容，我们得到使用加载更多的按钮

这是我的密码：

    import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.io.Writer;
import java.net.MalformedURLException;

import com.gargoylesoftware.htmlunit.BrowserVersion;
import com.gargoylesoftware.htmlunit.FailingHttpStatusCodeException;
import com.gargoylesoftware.htmlunit.NicelyResynchronizingAjaxController;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HtmlPage;


public class Sample {
    public static void main(String[] args) throws FailingHttpStatusCodeException, MalformedURLException, IOException, InterruptedException {
        String url = "https://communities.netapp.com/welcome";
        WebClient client = new WebClient(BrowserVersion.INTERNET_EXPLORER_9);
        client.getOptions().setJavaScriptEnabled(true);
        client.getOptions().setRedirectEnabled(true);
        client.getOptions().setThrowExceptionOnScriptError(true);
        client.getOptions().setCssEnabled(true);
        client.getOptions().setUseInsecureSSL(true);
        client.getOptions().setThrowExceptionOnFailingStatusCode(false);
        client.setAjaxController(new NicelyResynchronizingAjaxController());
        HtmlPage page = client.getPage(url);

        Writer output = null;
        String text = page.asText();
        File file = new File("D://write6.txt");
        output = new BufferedWriter(new FileWriter(file));
        output.write(text);
        output.close();
        System.out.println("Your file has been written");  

       // System.out.println("as Text ==" +page.asText());
      //  System.out.println("asXML == " +page.asXml());
      //  System.out.println("text content ==" +page.getTextContent());
      //  System.out.println(page.getWebResponse().getContentAsString());
    }
}

有什么建议吗？

我从你的问题中了解到，你有一个按钮需要按下

请看:

这里有一个提交表单的示例

这里应该非常相似
